Abstract
A cyclic adsorption process for the fractionation of a gaseous mixture, over an adsorbent exhibiting differential rates of adsorption for the components of the gaseous mixture. The process delivers a product gas of a constant concentration by varying the length of time of the adsorption phase and the rate of flow of the product gas from the adsorber, in response to a varying demand for the product gas. The rate of flow of a feed gas is varied in relationship to the rate of flow of the product gas. The rates of flow of the feed gas and of the product gas and the length of time of the adsorption cycle are determined from a correlation of the rate of flow of the product gas as a function of the product gas purity. The correlation is established experimentally for each feed/product gas combination.
